3. " Description and Correlation of the Bournemouth Beds. — 

 Part II. Lower or Freshwater Series." By J. S. Gardner, Esq. 



This was in continuation of a former paper by the author 

 (Q.J.G.S. vol. XXXV. p. 209). The beds described are exposed east 

 and west of Bournemouth and near Poole harbour, over a distance of 

 about four miles. The author referred them to the Middle Bagshot, 

 and stated that they are distinguished from the Lower Bagshot by 

 the absence of the extensive pipe-clay deposits and the presence of 

 brick-earths, and from the overlying beds by the absence of flints. 

 They reach their extreme limit in the western area of the London 

 basin, and are represented by the lignitic beds 19-24 of Prof. Prest- 

 wich's section. Lignites can be traced p)artly across the bay. The 

 cliffs present an oblique section across a delta divisible roughly into 

 four masses, one of which, from its confused bedding and want of 

 • fossils, is supposed to have been formed by the silting up of the main 

 channel. The total thickness of the series was estimated at 600 to 

 700 feet. The inferences drawn by the author were as follows : — 

 1. Prom the beds cut through showing a steep side to the west, 

 that the river flowed from that direction ; 2. Prom the absence of 

 boulders or coarse sediment, that the area was flat ; 3. Prom the 

 absence of lignite, that there were catchment basins ; 4. Prom the 

 absence of flint and the quartzose nature of the beds, that no chalk 

 escarpments were cut through, and that the deposits came from a 

 granitic area ; and 5. Prom the presence of wood bored by Teredo, 

 that the beds belong to the lower part of the river in proximity to 

 tidal water. 



The flora was stated to be confined to local patches of clay. Those 

 at the western end of the section are very rich, and distinguished 

 from the rest by absence of palms and rarity of ferns. The beds 

 near Bournemouth are still richer and very distinct ; those east of 

 Bournemouth are characterized by Eucalypti, Aroids, and Araucarice ; 

 and those at the western end of the section by abundant Polypo- 

 diaceaj. It is remarkable that nearly every patch contains a flora 

 almost peculiar to it ; but the flora as a whole seems to pass upward 

 to the Oligocene, but not down to the Lower Bagshot.

" KAMMPLATTEN " IN THE lEONSTONE OF BOEOUGH LEE. 

 Sir, — I have now no doubt that the pectinated object from the 

 Ironstone of Borough Lee, which I at one time supposed might 

 possibly be a tooth, and in a recent Number of your Magazine 

 (January, 1881) I described under the name of Euctenius elegans, 

 belongs in reality to the same category as the " Kammplatten," 

 which Prof. Anton Pritsch, of Prag, has recently described and 

 figured as appertaining to the cloacal region of certain fossil 

 Aniphibia, e.g. OpMderpeton pectinatum (Pritsch, Pauna der Gaskohle 

 und der Kalksteine der Permformation Bohmens, Bd. 1, Heft 2,
